Abstract

There is provided a process for producing high molecular weight polymer comprising the step of reacting one or more preformed linear polymers with one or more cores (as hereinbefore defined) to form high molecular weight polymers, wherein the preformed linear polymers are at a temperature in the range from the melting point of the preformed linear polymers to 330° C.
